An API wrapper for WiringPi to make it accessible using Rust. It implements the most important functions and provides a bit of type system convenience.

Add the following lines to your Cargo.io to use rust-wiringpi:

[dependencies]
wiringpi = "0.2"

Released

Master branch

extern crate wiringpi;

use wiringpi::pin::Value::{High, Low};
use std::{thread, time};

fn main() {
    //Setup WiringPi with its own pin numbering order
    let pi = wiringpi::setup();

    //Use WiringPi pin 0 as output
    let pin = pi.output_pin(0);

    let interval = time::Duration::from_millis(1000);

    loop {
        //Set pin 0 to high and wait one second
        pin.digital_write(High);
        thread::sleep(interval);

        //Set pin 0 to low and wait one second
        pin.digital_write(Low);
        thread::sleep(interval);
    }
}

rust-wiringpi can also wrap the WiringOP library for the Orange Pi SBC boards. This can be enabled with the orangepi feature:

[dependencies.wiringpi]
version = "0.2"
features = ["orangepi"]

In development mode, rust-wiringpi is compiled as a rust-native library excluding the original WiringPi. And binding functions are replaced by dummy functions that output simple logs to stdout. With this mode, you can build and debug your project on platforms that does not support WiringPi.

Development mode will be turned on automatically on non-arm targets, but can be turned on manually on arm targets as well
